All diet cultists are moronic cretins that think they will live forever and actually matter on the cosmic scale.
Imagine being such a fricking low IQ slave that you block yourself from enjoying varieties of foods. There is so much to try in this world before you inevitably bite the dust and shit your pants in regrets on your deathbed. BUT NAAAH, I'M A vegan I'M ON KETO. Fricking cretins.
Manmade concept that doesn't apply in nature. Animals slaughter each other without any second thoughts or remorse(once again, shitty human mental illness strengthened by Abrahamic slave cults). A herbivorous animal will eat meat given the chance.
If you starve yourself with specific diet for some imaginary "greater good" then you're anti-nature, to be anti-human, is to be anti-animal. If you vegans care so much about animals, then stop breathing, you're stealing oxygen from the poor animals.
